我有两张桌子tbl_PurchaseDetails和tbl_ItemDetails. tbl_ItemDetails我需要在from中插入一些行tbl_PurchaseDetails，就在它插入之后tbl_PurchaseDetails。我知道这个问题，但我无法解决它。请帮忙。

我为触发器编写了以下代码：

CREATE TRIGGER trigger_UpdateItemDetails ON tbl_PurchaseDetails
FOR INSERT AS
DECLARE @PurchaseID VARCHAR(20)
DECLARE @Quantity INT
DECLARE @WarehouseID VARCHAR(20)

SELECT @PurchaseID=(PurchaseID) FROM INSERTED
SELECT @Quantity=(ItemQuantity) FROM INSERTED
SELECT @WarehouseID=(WarehouseID) FROM INSERTED

INSERT INTO 
tbl_ItemDetails
(PurchaseID,Quantity,WarehouseID)
VALUES
(
@PurchaseID,@Quantity,@WarehouseID
)

现在，当我插入tbl_PurchaseDetails行时，添加到tbl_PurchaseDetails但不添加到tbl_ItemDetails. 它抛出以下错误：

消息 515，级别 16，状态 2，过程 trigger_UpdateItemDetails，第 11 行
无法将值 NULL 插入列“PurchaseID”，表“dbStockHandling.dbo.tbl_ItemDetails”；列不允许空值。插入失败。

我的问题是如何获取插入的值，tbl_PurchaseDetails以便触发器可以将它们插入tbl_ItemDetails？

请试试：

CREATE TRIGGER trigger_UpdateItemDetails ON tbl_PurchaseDetails
FOR INSERT AS
BEGIN

    INSERT INTO 
    tbl_ItemDetails
    (
        PurchaseID,
        Quantity,
        WarehouseID
    )
    SELECT 
        PurchaseID, 
        ItemQuantity, 
        WarehouseID
    FROM 
        INSERTED
END

并确保您在tableNOT NULL的列中插入一个值。PurchaseIDtbl_PurchaseDetails
